WINDOW-SCREEN.

Application filed August 21, 1318.

To all whom it may concern.

Be it known that I, ARTHUR G. SoULn, a citizen of the United States, and a resident of the city and county of San Francisco, State of California, have made a new and useful invention--to wit, Improvements in lVindow-Screens; and I do hereby declare the following to be a full, clear, concise, and exact description of the same.

This invention relates more particularly to sliding window screens adapted to be pivoted within the window opening.

Among the objects of this invention are to produce a window screen simple and cheap in construction, that may be readily installed and removed from the window casement.

in this specification and the annexed drawings, the invention is illustrated in the form that is considered to be the best, but it is to be understood that the invention is not limited to such. form because it may be embodied in other forms, and it is also to be understood that in and by the claims following the description it is desired to cover the invention in whatever form it may be embodied.

The present structure is particularly adaptable to window openings fitted with pivotal or casement window sashes, in which it is often necessary to put the screen within the interior portion of the window casement. The construction. illustrated represents a combination of frames, inter-connected and slidable upon each other in such a manner, that the combined thickness of the screen frames is kept within the limit of sightliness and the available space for installing the screens. It is important also that the screen be easily opened, giving ready access to the window sash; and that the whole screen may be quickly and easily ren'io-ved from the window frame without leaving the window opening unsightly, by reason of the nature of any permanent element of the screen remaining during that season of the year that window screens are unnecessary.

In the accompanying one sheet of drawing:

illustrate the interior arrangement of the parts.

Fig. 2 is a perspective view looking to ward the upper ends of the sash members.

Fig. 3 is an enlarged detail view of the connecting guide rail plate.

Fig. I is a detail in perspective of the suspending hook attached to the screen.

In detail the construction illustrated in the drawing includes two or more screen frames of conventional construction provided with the usual wire mesh screen.

The 'upper'frame is composed of the stiles 1 and 2 joined by the top rail 3 and a lower meeting rail forming a rectangular frame of the approximate width of the window opening between the side stops of the casement. The lower frame is similar to the upper just described, comprising the-stiles 5 and G joined by the bottom rail 7 and the meeting rail 7. The edges of the side rails and 6 are provided with longitudinal grooves 8-8 continuing throughout their length. These grooves engage the guidehead 9 formed on the joining plates 10 fixed to "the outer edges of the stiles 1 and 2 of the upper frame, by means of screws passing through the holes 11 provided in the plate 10. These plates 10 are fixed to opposite sides of the upper frame so that approximately half their length extends beyond the lower or meeting rail of the upper frame to guide the lower frame when the screen in the extended position with the meeting rails of the respective frames in registry. The joining plates 10 are of a width equal to the combined thicknesses of the screen frames, the edge of the extension 12 coming flush with the surface of the lower frame, in order to provide a friction bearing surface for the whole edge of the screen frame.

To provide the necessary friction for holding the two screens in adjusted relation to each other, the flat spring 13 is attached to the guide bead 9 and bears against the bottom of the slot formed in the rail 6 of the lower frame. It is sufficient to provide one of such springs on one side only of the assembly. The compression of the spring between the bottom of the slot 8 and the face of the guide heads 9 forces the edge of the side rail 5 against the plate 10 on the opposite side of the frame, withv sufficient pre sure to exert a friction that will hold the if two frames in any adjusted relation. The

spring 13 is very economically attached to the guide bead 9 by slotting the latter transversely as at 14:, inserting one end of the spring 13 and crimping the sides of the guide bead 9 as at 15 to bind the ends of the, spring'in permanent position, the opposite end of the spring sliding freely upon the surface of the bead 9 when the spring is compressed. The metal of which the joining plates is composed is sutliciently thin not to interfere materially with the insertion of the combined frames within the window casement, avoiding the necessity of gaining the plates into the side of the frame.

The upper corners of the upper frame are provided with the plates 16-16 screwed thereto and provided with a hook 17 adapted to hook behind and over the screw studs 18-18, preferably consisting of ordinary round head screws fixed in the side stops near the top of the window opening, at the proper level so that the top rail 3 will approximately contact with the lintel of the window casing. To prevent the upper rail 8 of the lower frame risin into contact with the studs 18 the plates 16 are provided with bosses 19 projecting from the surface thereof to act as stops to limit the rise of the lower frame. The lower rail 7 is provided with a handle 20 for manipulating the lower frame. In closing the window opening, the lower frame is raised and swung into the vertical position and lowered, the grooves 88 engaging the studs 21 of any suitable character attached to the side stops to retain the whole screen in the vertical position when closed.

When it is desired to manipulate the window sashes, the lower frame is slid upward on the guide plates 10 permitting access to the sashes of the window. When it is de sired to remove the screen fromthe window opening, it is collapsed by sliding the lower frame upward over the upper frame, then swinging the assemblage inwardly until the hooks 17 disengage from the studs 18, the studs 18 and the studs 21 being the only permanent fixtures attached to the window casement to assemble the screen therein.

Having thus described this invention, what I claim and desire to secure by Letters Patent is: I a

1. A screen including a plurality of overlapping frames, and plates secured to one of said frames having guide beads engaging Copies of t his patent may be obtained for grooves in the lateral edges of the other frame.

2. A screen including a plurality of overlapping frames; guide plates secured to one of said frames and engaging grooves in the lateral edges of the other frame; and a resilient friction member interposed between said grooves and said plates.

3. A screen including a plurality of over lapping frames; guide plates secured to the opposite edges of one of said frames and having guide beads thereon slidable in grooves formed in the lateral edges of the other frame; and a resilient friction member interposed between one of said plates and the edge of the contiguous frame.

A screen including a plurality of overlapping frames, plates secured to one of said frames having guide beads engaging grooves in the edges of the other frame, and hook plates on the upper corners of the upper screen adapted to engage studs in a window casement.

5. In combination with a window casement, top and bottom studs in said casement; a top screen frame having hooks pivotally engaging said top studs; a bottom screen frame having grooves engaging said bottom studs; and guide plates fixed on said top frame and slidably engaging said grooves in said bottom frame.

6. In combination with a window casement, top and bottom studs in said casement; a top screen frame having hooks pivotally engaging said top studs; a bottom screen frame having grooves engaging said bottom studs; guide plates fixed on said top frame and slidably engaging said grooves in said bottom frame, and a resilient friction member fixed to one of said guide plates within said groove.

7. In combination with a window casement, top and bottom studs in said casement; a top screen frame having hooks pivotally engaging said top studs; bosses projecting laterally from said hooks, a bottom screen frame having grooves engaging said bottom studs; and guide plates fixed on said top frame and slidably engaging said grooves in said bottom frame whereby said bottom frame may slide over said top frame and stop against said bosses.

In testimony whereof, I have hereunto set my hand at Washington, D. (1, this 8th day of August, 1916.
